' 4 claims. (o1. ess-187) This invention relates to an apparatus for dyeing wool in its different forms, such as raw material, yarn, spools, skeins, tops or the like.

The object of this invention is to provide an apparatus whereby such material can be dyed so that it will remain soft throughout-and will not tend to felt on its surface, and whereby a uniform treatment of the material by the dye liquor will be obtained.

Another object of this invention is to provide a construction whereby the quantity of dye liquor can be easily regulated to be inl proper proportion to the volume of the material toloe dyed, so that a considerable saving of the relatively expensive dye chemicals, heat and water will be obtained.

Another object is to provide an apparatus of extremely simple construction and of such simple operation that a number of such machines or apparatus can be controlled and attended to by a single person. Y v

With these and otherobjects in'view my invention consists ofthe novel construction, combination and arrangement of parts as will be hereinafter more fully described andv dened in Figure 1 is a vertical section of my apparatus,

and

Figure 2 is a cross section on line 2-2 of Figure 1.

The apparatus comprises an open topped tank I0 of rectangular shape which by a vertical partition is separated into two chambers, chamber Illa serving to receive the material to be treated and chamber ||a serving to receive the dye liquor and also heating means. The partition rising from the bottom terminates somewhat below the upper edge of the tank.

At a suitable elevation from the bottom of the tank within the chamber |0a a compartment l0' is formed, which is provided with a horizontally extending perforated surface such as a netting or mesh l2 to support a certain volume of the material to be treated in said compartment. The space above said support is provided with means whereby it can be quickly and conveniently separated into a number of vertically superposed additional compartments |02, |03, and |04, each to receive additional volumes of the material to be treated. To this end each of two opposite walls of the chamber Illa may be provided with' grooves I3, the corresponding grooves in the two walls being in alignment with one another and capable of slideably and removably engaging a plurality of beams or bars I4 to be spaced from one another. These beams or bars are adapted not only to separate the divers compartments from one another, but also to compress the vmaterial deposited in the compartment below them and to hold the material in compressed and stationary condition during the dyeing process.

For the support of the material in each of these compartments perforated sheets or nettings |2a are removably mounted on said spaced bars.

In the'example shown the grooves I3 are advantageously formed each by a pair of ribs |3a|3b of which rib |311l is somewhat shorter to form a gap |30 through which the bars can be easily slid into position within the grooves.

Thus in addition to the volumeof material deposited on the perforated surface l2v additional volumes of such material may be packed in one or more of the compartments, l0', H32, or |03.

The partition II is provided with a number of4 jopenings I'Ia arranged in alignment with the divers compartments and capable of being closed by doors I6. These doors are suitably hinged at Isa. to said partition or otherwise movably supported thereon and may be provided with gaskets |1 to produce tight closure. Clamping screws I8 are provided to hold the doors in closed position. A pipe |9 for the admission of water into the chamber ||a terminates at the upper end of said tank. Leading into and downwardly through the chamber Ila is a steam pipe 20 for heating the dye liquor.

The lower portion of the partition is provided centrally with a circular opening ||b in which s mounted an impeller 2| or the like which may be suitably propelled from -a motor 22 and which serves to circulate the dye liquor through the material to be dyed.

In the drawing two compartments in the chamber Ia are shown to be packed with the material t-o be dyed. In that case the openings Ia of the empty compartments are open while the door of :the packed compartment is closed. If the next higher compartment is also to be packed its opening too will be closed.

The material is deposited on the perforated surfaces I2, |2a then covered by another perforated surface |2b and compressed by the beams or bars I4.

In opera-tion water in proportion to the volumes of material to be :treated is admitted into .the chamber Ia, and a proportionate amount of the dye stui is dropped into the water. After admitting steam through the pipe the impeller 2| is set into motion through the motor 22 as a result of which the dye liquor will be caused to circulate from the chamber I la `through the material packed in the ch-amber Illa.

Since various changes may be made in the construction of my Iapparatus Without departing from the underlying principle thereof, I do not Wish to restrict myself to the details described and shown except as limited bythe scope of the claims.

What I claim is:

l. An apparatus of the character describedA comprising a tank divided laterally into two separate chambers. one serving to ,receive the material to be treated and the other to receive the dye liquor, opposite Walls of said tank having each a vertical set of horizontal grooves, a perforated support in said first named chambermounted Iat =an elevation from the bottom thereof, said tvvo chambers having controllable passages above said perforated support, Ameans for compressing the material and holding it in compressed and stationary condition during the dyeingprocess. said means including members removably and slidably borne in said grooves, to divide said material receiving chamber into separate compartments, said passages being in align- Vmen-t with said separate compartments, means for continuously and uniformly heating the dye liquor and means for causing the circulation of the dye liquor through the material to be dyed. 2. In an apparatus of the lcharacter' described, a tank formed laterally With -a dye liquor receiving chamber, a perforatedsupport for the material to be :treated in said tank mounted at an elevation from the bottom thereof, means for separating the space `above said perforated support into. several vertically superposed compartments each ladapted to receive an addi-tional volume of the material to be treated, said means including a plurality of members capable of removably engaging 'opposite Walls of said tank, perforated supports adjusted to be VremovablyA mounted on said members, the latter serving also to compress the material deposited in a compartment below and hold said material in compressed and stationary condition during the dyeing process, heating means in said chamber and means for -causing the circulation of the -dye liquor through the material to be treated, said tank having controllable openings leading into said dye liquor receiving chamber and arranged in alignment With said superposed compartments.

3. In an apparatus of the character described, a tank divided by a vertical partition having controllable passages into two separate chambers, one serving .to receive the material to be dyed and the other to receive the dye liquor, a perforated support for the material in said rst named chamber above the bottom thereof, vertical sets of supports on sai-d partition and the opposite Wall of said iirst named chamber, members-removably and slid'ably engaging said supports `and serving to subdivide said first named chamber into av plurality of compartments for |additional volumesvof material to rbe dyed,rsaid controllable passages leading from said compartments into said dye liquor receiving chamber and being in alignment with said compartments, and means between said last named chamber and the space below said perforated support,for impelling the dye liquor. to circulate through lthe material to be dyed. f v

4. In an apparatus of the character described, a tank formed withA a dye liquor receiving Lchamber, a perforated support for the materialt be treated in said tank, removable means for4 separating the. space above said perforated support into -a plurality of vertically superposed compartments each adapted to receive an additionalvolf ume of material -to be. treated, heating means in said chamber, means for causing circulation of the dyeing liquor through the material-to be treated, said tank having controllable passages leading into said liquor receiving chamber and arranged in alignment with said superposedycompartments.
